LAMP ATTACHMENT.

Specification Letters Patent.

Patented June 15, 1909.

Application filed April 6, 1908. Serial No. 225,569.

To all whom it may concern:

it known that we, \Vorowsn'i V. VJIL- LlAMS and VViLLiAM K. LANE, citizens of the United States, residing at Goldsboro, in the county of Wayne and State of North Carolina, have invented certain new and useful improvements in Lamp Attachments, of which the following is a specification.

This invention contemplates certain new and useful improvements in that type of lamp attachment designed to support a vessel above the lamp so that it may be heated by the latter, may be desired for cooking or vaporizing purposes or the like; and the object of the invention is an improved device of this character which may be applied to lamps of different sizes, and which is more effective than the ordinary form of device, since it is arranged so that the heat from the lamp will be evenly and quickly distributed at the heated surface of the vessel.

For a full understanding of the invention and the merits thereof and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawing, in which:

Figure 1 is a side elevation illustrating the application of my invention; Figs. 2 and 3 are perspective views of the respective supports detached; Fig. 4 is a similar view showing the supports associated and, Fig. 5 is a detail perspective view illustrating a modi iication hereinafter described.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing, by the same reference characters.

This improved device comprises two supports 1 and 1 which are formed at their upper ends with oppositely disposed wings 2, said supports being frame-like in construction, and for this purpose, being formed. within their margins with longitudinal openings 3 that are laterally enlarged at their upper ends so as to extend into the wings 2. Each of these frame-like supports embodies an upper cross bar 4 which defines the upper wall of the opening 3, and a lower cross bar 5 which defines the lower wall thereof, said lower cross bar being preferably widened, as shown, and the upper cross bar being widened at its middle point and in alinement with the lower cross bar, as indicated at 6.

The lower cross bars and the widened portions of the upper cross bars are formed with longitudinally disposed slits 7 leading from one edgethereof and extending almost to, but terminating short of the opposite edge, the slits of the cross bars of the support 1 leading from the opening 3, and the slits of the other support 1 leading from the outer edges of the respective cross bars as shown. The slitted portions of the cross bars are arranged for an interlocking engagement, so as to detachably secure together the supports, and hold the latter in perpendicular relation to each other.

In the practical use of our improved de vice, the latter is applied to a lamp in the ordinary manner with the lower portions of the supports extending downwardly into the lamp chimney, and the lower edges of the wings 2 resting against the upper end of the same to sustain the device in position, the said lower edges of the wings being preferably serrated, as indicated at 8, so as to pre vent the device from slipping. The vessel that it is desired to heat is then placed upon the upper edges of the upper cross bars l, the heated air from the lamp ascending in the chimney and contacting with the vessel and being thus utilized to heat the same.

In order to effect an even distribution of the heated air at the surface of the vessel, the upper edges of the upper cross bars 4 are recessed, as shown at 9, so as to permit cross currents of heat, the openings 3 in the supports also serving to distribute the heat and to render possible a center draft in the lamp chimney.

When the two supports 1 and 1 are associated or in operative position, as illustrated in Fig. 4, the unslitted portion of the cross bars between the terminals of the slits and the opposite edge, are received in the slits in the corresponding cross bars of the other support to effect an interlocking connection between the supports and limit the relative movement of the same, it being noted, however, that since the slits 7 extend almost to the opposite edges of the cross bars, said slits are longer than the distance between the ter minals of the same and the opposite edges, and hence the unslitted portions are adapted to work back and forth in the slits in which they are mounted, to render possible a slight relative longitudinal movement of the supports. In order to effect the disengagement of the supports, when it is desired to knock down the device for any purpose, it is only necessary to raise the support 1 relative to the other support as far as possible, that is until the terminals of the slits 7 in the upper cross bars 4 abut. 'lhis movement of the support 1 is suflicient to slide the slit 7 in the lower cross bar 5 thereof out of engagement with the unslitted portion of the corresponding cross bar of the other support 1 and the lower end of the cross bar 1 is then moved laterally through the slit 7 in the corresponding cross bar and is thus entirely disengaged therefrom, whereupon such support 1 may be drawn downwardly to disengage the interlocking upper cross bars 4 and to withdraw the upper portion of the support 1 through the opening 3 in the other support.

The rengagement of the parts may obviously be effected by reversing the above operation.

From the above description, in connection with the accompanying drawing, it will be apparent that we have provided a simple, durable and efficient construction of device which may be readily knocked down when desired, by disengaging the interlocking cross bars, and which consists of co1nparatively few parts that may be easily and cheaply manufactured, as by being stamped out of sheet metal, and that may be readily assembled.

Fig. 5 shows another embodiment of the inventlon which is the same in construction as the form 01 the device above described,

but which differs in design, particularly in the form of the serrations 8 and the recesses 9.

Having thus described the invention, what we claim is:

A heating attachment for lamps, comprising frame-like supports formed at their upper ends with oppositely and laterally disposed wings, said supports being formed with 1ongitudinal openings and embodying upper and lower cross bars, the cross bars of one of the supports being formed with slits leading from the opposing edges of the same and the cross bars of the other support being formed with slits leading from the outer edges thereof and arranged for an interlocking engagement with the oppositely slitted cross bars, as and for the purpose specified.

In testimony whereof we aflix our signatures in presence of two witnesses.
